Answer:
False
Step-by-step explanation:
because trigonometric identities are true for ALL angles, whereas trigonometric equations are NOT true for ALL angles.
Answer: B
Work:
Since the general formula of an arithmetic sequence is f(n) = (the first term) + (common difference)*(n-1), you just plug in what was given to you in the problem to that equation. The first term is -20 and the common difference is +15 since the the increase from one term to the next is 15. Doing so produces the equation f(n) = -20 + 15(n-1), which is choice B.
Answer:
the answer to this would be $5.20
Step-by-step explanation:
0.40 times 13 = 5.20
Answer:
D. Undefined
Step-by-step explanation:
Since there is nothing that we can raise 3 to in order to get -5, we know that this is undefined. This is true of all logs with a negative number in front.
